Abstract: A routing device is provided for transporting digital data from demodulated digital television signals. The routing device includes a network that routes the digital data to demultiplexers via at least one decoding module. The network includes means for connecting to at least two independent demodulation channels, with each of the demodulation channels producing digital data from a demodulator. The network allows individual routing of the digital data from each of the demodulation channels to the demultiplexers via at least one decoding module. Also provided are a corresponding routing method and a host device that includes such a routing device. Exemplary applications of the routing device and method are a digital television receiver with an image incorporation (picture in picture) function, and a digital television combined with a recording device.
